      使用其他的Image Loader
      <a class="edit-page-link" href="https://github.com/liaohuqiu/fresco-docs-cn/blob/docs/docs/03-using-other-image-loaders.md" target="_blank">编辑和纠错</a>
    </h1>
    <p></p>

    <p>Drawee is not tied to a particular image loading mechanism and can be used with other image loaders.
Drawee 并不是吊死在特定的一种图片加载机制上，它同样适用于其他image loader。</p>

<p>不过有一些特性，只有Fresco image pipeline才有。前面的提到的需要使用[ImageRequest]和[配置image
pipeline]的特性，使用其他image loader时都有可能不起作用。</p>

<h3>Drawee 和 Volley ImageLoader配合使用</h3>

<p>我们有一个Drawee使用Volley的 <a href="https://developer.android.com/training/volley/request.html">ImageLoader</a>的补充实现。 </p>

<p>我们仅仅对那些已经深度使用Volley ImageLoader的应用推荐这个组合。</p>

<p>同样地，如要使用，使用下面的依赖，而不是<a href="download-fresco.html">下载</a>页面给出的依赖:</p>
<div class="highlight"><pre><code class="language-groovy" data-lang="groovy"><span class="n">dependencies</span> <span class="o">{</span>
  <span class="c1">// your project&#39;s other dependencies</span>
  <span class="nl">compile:</span> <span class="s2">&quot;com.facebook.fresco:drawee-volley:0.1.0+&quot;</span>
<span class="o">}</span>
</code></pre></div>
<h4>初始化Volley ImageLoader</h4>

<p>这时，不需要再调用<code>Fresco.initialize</code>了，需要的是初始化Volley。</p>
<div class="highlight"><pre><code class="language-java" data-lang="java"><span class="n">Context</span> <span class="n">context</span><span class="o">;</span>
<span class="n">ImageLoader</span> <span class="n">imageLoader</span><span class="o">;</span> <span class="c1">// build yourself</span>
<span class="n">VolleyDraweeControllerBuilderSupplier</span> <span class="n">mControllerBuilderSupplier</span>
    <span class="o">=</span> <span class="k">new</span> <span class="nf">VolleyDraweeControllerBuilderSupplier</span><span class="o">(</span><span class="n">context</span><span class="o">,</span> <span class="n">imageLoader</span><span class="o">);</span>
<span class="n">SimpleDraweeView</span><span class="o">.</span><span class="na">initialize</span><span class="o">(</span><span class="n">mControllerBuilderSupplier</span><span class="o">);</span>
</code></pre></div>
<p>不要让 <code>VolleyDraweeControllerBuilderSupplier</code>离开作用域，你需要它来创建DraweeController，除非你只使用<code>SimpleDraweeView.setImageURI</code>。</p>

<h4>DraweeControllers 和 Volley ImageLoader 配合使用</h4>

<p>不是调用<code>Fresco.newControllerBuilder</code>, 而是:</p>
<div class="highlight"><pre><code class="language-java" data-lang="java"><span class="n">VolleyController</span> <span class="n">controller</span> <span class="o">=</span> <span class="n">mControllerBuilderSupplier</span>
    <span class="o">.</span><span class="na">newControllerBuilder</span><span class="o">()</span>
    <span class="o">.</span> <span class="c1">// setters</span>
    <span class="o">.</span><span class="na">build</span><span class="o">();</span>
<span class="n">mSimpleDraweeView</span><span class="o">.</span><span class="na">setController</span><span class="o">(</span><span class="n">controller</span><span class="o">);</span>
</code></pre></div>
<h3>Drawee 和其他Image Loader 配合使用</h3>

<p>依照<a href="https://github.com/facebook/fresco/tree/master/drawee-backends/drawee-volley/src/main/java/com/facebook/drawee/backends/volley">源码</a> 作为例子，其他Image Loader也是可以和Drawee配合使用的，但是没有我们还没有Drawee和其他Image loader的配合使用的补充实现。</p>
